Albatros Dr.II

The Albatros Dr.II was a German prototype single-seat fighter triplane, the sole example of which flew in the spring of 1918. It was similar in many respects to the D.X biplane, employing among other features the same 145 kilowatt Benz Bz.IIIb engine and twin 7.92 millimetre machine guns. The three pairs of wings were sharply staggered, braced by broad I-struts and sharing parallel chords, and all three pairs were equipped with ailerons linked by hinged struts. The published specifications give a length of 6.18 metres, a wingspan of 10 metres, a height of 3.34 metres, a wing area of 26.6 square metres, an empty weight of 676 kilograms and a gross weight of 915 kilograms.
